I don't see any reason why this would give an error, unless
programming error. A grad student here has successfully used
exactly these functions extensively in his (still unpublished) R package
-- for writing and reading large arrays of 'double' (numbers).

(why is that vague?) In any case, Rprintf() and REprintf() are
clearly for writing to "the console" / "the error stream"
--
where these latter terms are specific for the platform and the
way R was called on the platform.
